Some research has shown that women's achievements in traditionally masculine fields are devalued. To determine if females would be judged more harshly than males for performing unethical behaviors in order to gain entry in competitive professions, and to examine gender differences in the evaluation of unethical conduct, college students (52 males and 142 females) were presented with vignettes of male or female pre-medical students who cheated on an exam and either were caught or not caught. The students then responded to questions regarding the protagonists' personality traits, future success and competence as physicians, frequency of past cheating behavior, and reasons and appropriate punishment for the cheating behavior. Statistical analyses showed a slight own-gender bias on the part of males. Men rated uncaught protagonists higher in the trait "good," while women rated the caught protagonists higher in this trait. Men recommended more severe punishment for cheating than did women, and both men and women predicted that the uncaught protagonists would be more successful physicians. Overall, little gender bias favoring the male protagonist was found. The vignette text and brief rating scale are appended. (WAS)
